Researchers claim that a Raspberry Pi's Wi-Fi can provide "clinical-level heart rate monitoring" without the need for a wearable

Wi-Fi signals and machine learning can noninvasively process heart rate with clinical-level accuracy in under 5 seconds. After being tested on 118 people, it read pulse during motion using a $30 ...
